The spark electrode generates the high-voltage arc that ignites the gas burner during each heating cycle. When the electrode degrades, cracks, or becomes carbon-fouled, the unit will attempt ignition, fail to light, and go into a safety lockout — leaving your space without heat. Replacing the electrode with a genuine OEM assembly restores factory-reliable ignition every time.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Spark electrode (2-rod) ignitor assembly | Factory Authorized Part | OEM Part Numbers: 48GS400168 (primary in-production) \/ 48VL400002 (superseded) | Designed for packaged rooftop gas-electric units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM electrodes are manufactured to exact gap, material, and wire-length specifications.
